Re: [ros-diffs] [greatlrd] 26246: fixing the build for gcc 3.4.5

[gerard.murphy]

Why have all these 'initialization bugs' suddenly been highlighted, and only
in GCC 3.4.5

Has the latest PSEH code highlighted a GCC 3.4.5 issue which we are just
hiding by double initializing variables??
We've seen initialization bugs with 3.4.5 before but always ignored them as
they appear in development. This is on a different scale.

Taking the AFD as an example, as this was also briefly batted around in IRC,
line 769 holds:

PDEVICE_OBJECT DeviceObject;

Line 773 then holds:

DeviceObject = IoGetRelatedDeviceObject(TransportObject);

This is before any calls to _SEH_TRY, so it's not an issue of stuff being
wrapped in PSEH 

In the words of Mr. Poussineau
- if error message is correct, fix the bug
- if error message is incorrect, report to GCC

Therefore as this code is not a real error, we should either send a bug
report off to mingw, or more realistically, drop 3.4.5 and move to 4.1.2 (as
the latest RosBE already does).
We shouldn't really be hiding incorrect errors by double initializing.

Ged.
